Double galaxies in galactic clusters

We have identified 127 galactic pairs in six of Abell's rich galactic clusters. We have established positive correlations between certain parameters of the components of the pairs. We conclude that, despite the gravitational influence of other members of the cluster, a subsystem of double galaxies exists in rich clusters as a structural element of these structures.Translated fromAstrofizika, Vol. 37, No. 3, 1994.The author is grateful to L.
